Factors to consider while buying a 1.5-ton 5 star split AC

That said, there are a lot of factors beyond the energy rating that users need to factor in while choosing the right 1.5 ton split AC for their homes. Here are the most important ones:

- ISEER Rating: Look for a high Indian Seasonal Energy Efficiency Ratio (ISEER) rating. For a 5-star split AC this value should be 4.5 and above.

- Inverter Technology: Look for ACs with inverter technology adjust compressor speed based on heat load. This provides steadier cooling and can save up to 30-50% on electricity bills compared to non-inverter models.

- Temperature support: Indian summers are getting brutal every year, which means regular ACs that support cooling at up to 48-degrees Celsius won't be enough. So, look for ACs that can provide cooling when temperatures cross the 50-degrees Celsius mark..

- Condenser Coil Material: Always opt for 100% Copper coils. Copper offers superior heat transfer and is easier to repair compared to aluminum.

- Convertible Modes: Look for features like 5-in-1 or 7-in-1 convertibility. This allow you to adjust the cooling capacity of the compressor based on the cooling load, which in turn saves energy and helps reduce electricity bills.

- Air Filtration system: Lastly, look for ACs with high-quality filters such as PM 2.5 or PM 0.1. These are essential for removing dust and allergens from indoor air.

So, if you are looking for a 1.5-ton split AC for your home, I have curated a list of the best 1.5-ton 5 star split ACs in India for you. I have curated this for you based on the factors mentioned above. I've also used hundreds of ACs, both split and window models, read a bunch of Reddit posts on the technologies used in modern AC, materials used and their efficiency and energy rating system in India, and gone through buyers' reactions on Amazon.
